Original application filed June 1, 1909, Serial No. 499,467. Divided and this application filed April 5, 1910. Serial No. 553,647.

To all whom 'Lt may concern.:

Be it known that we, VILLIAM I'I. HALL and JOHN E. DwYER, residing, respectively, at Cincinnati, in the county of Hamilton and State of Ohio, and at Newport, in the county of Campbell and State of Kentucky, have jointly invented certain new and useful Improvements in Safes, of which the following is a specification.

This application is a division of our application for patent on improvements in safes, filed June l, 1909, Serial No. 499,467, to which reference is hereby made.

Our invention relates to safes, especially to the character of safes known as burglarproof safes, and has for its object the provision of means for retarding ingress to the interior of the safe, while permitting ready treatment of the door of the safe and its convenient assembling.

Our invention is designed primarily for application to so-called manganese safes, the material whereof has been subjected to a manganese process or treatment which renders the metal especially tough and hard, resulting in difficulty or impossibility in machining the metal thereof by means of metal tools, but it is obvious that the same may be applied to safes of different or other material.

In practice, in the process of treatment of the metal for producing` manganese safes, the depth below' the surface of the metal to which the hardening and toughening process reaches is limited, this depth being at present about one and a half inches. In our improved device we provide a door having an inner member and an outer member spaced apart and so arranged that they may be connected after treatment, thus enabling the adjacent walls of the door-members to be subjected to the direct action of the treatment for producing members of great ingress-resisting qualities.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is an axial section of our improved device taken on a line corresponding to the line z-z of Fig. 2, the body of the safe being partly broken away. Fig. 2 is a vertical section of the same taken on a line corresponding to the line g/-g/ of Fig. 1.

Fig. 3 is a similar section of the same on a line corresponding to the line mof Fig. 1. Fig. 4L is a detail in cross-section on the line w-w of Fig. 2. Fig. 5 is a similar detail on the line /v-v of Fig. 2. Fig. (3 is a crosssection of our improved device taken on the irregular line iff-a of Fig. 2. Fig. 7 is a detail in front elevation showing the position of the combination-lock. Fig. 8 is a detail in cross-section on the line t-#t of Fig. 2, but showing a modified form of joint for the connecting-members; and, Fig. 9 is a per. spective view of one of the connecting-blocks having a modified form of joint thereon.

1 represents the body of the safe and 2 the door thereof. The door comprises an inner member 3 and an outer member Ll. The body and the inner and outer doormembers are preferably composed of manganese or other treated steel for producing an especially hard and tough texture which is not responsive to the action of drills or other metal tools and which we shall hereinafter refer to as treated metal.

In a safe, the door is the part most vnlnerable to attack by burglars and in order to provide a door as nearly invulnerable as possible, we have provided an outer member which is separated from the inner member so that the door may be subjected to the treatment not only at the inner and outer faces of the door, but also subjected to the direct treatment at the adjacent faces of its members. Thus the outer member is provided with an outer face 5 and an inner face 6 and the inner member is provided with an outer face 7 and an inner face 8, the inner face 6 of the outer member and the outer face 7 of the inner member being adjacent faces, which are spaced apart, as indicated by the space 9, between the same.

The door-members, being subjected to treatment as stated, are rendered practically invulnerable to the action of metal tools, and we therefore prefer to provide connecting means between said members of material other than said treated material, which is capable of being acted on by metal tools for producing economy in manufacture and an article of superior proof against burglarizing, the connecting means being located between the door-members. These connecting means are shown as comprising interlocking joints 10.

We prefer that the connecting means between the inner and outer door-members shall be made of material other Vthan the treated material of which said door-inembers are composed and to provide said doormembers with inserts of material other than the treated material of which said doormembers are composed, and to secure the connecting-means between the door-members to said inserts, these connecting-means and inserts being of a material which is susceptible to action by metal tools, for instance tool-steel.

In the preferred form of our improved device, the inner door-member is provided with blocks 12 which may have connecting webs 13 and a connecting web 14 between the same, there being recesses 15 16 between said blocks. The outer surface of the inner doormember has inserts 17 in the same, these inserts being of greater cross-section at their embedded portion than at their outer ends, instanced by enlargements 18, for preventing the withdrawal of said inserts from said inner door-member. Screws 19 connect the blocks 12.with the inserts 17 the bolts being threaded into internally threaded sockets 20 in said inserts.

The inner face of the outer door-member is provided with blocks 21 having recesses 22 23 between them. For securing the blocks 21 to the outer door-member we provide the inner face of the latter with inserts 24 which also have enlargements as shown at 25 einbedded in said outer door-member for preventing the disengagement of said inserts. Screws 26 connect the blocks 21 with said inserts. cast about the inserts.

The blocks on the door-members in one form of construction which we have shown, (see Figs. 1 and 5), respectively have mating faces shown at tapered under-cut or dove-tail faces. These faces are shown as comprising tapering port-ions 29 and shoulders 30, the tapering portions insuring firm approach between the door-members when connecting the same, and said shoulders limiting said approach and preventing tilting of the outer upon the inner door-member. The faces respectively on the inner and outer door-members with which said blocks are arranged to contact are preferably fitted grinding by means of emery-wheel or the 1 ze.

In another form of construction which we have shown, (see Figs. S and 9), 4the blocks 12 21 between the door-members have mating faces 33, shown as serrated in cross-section, the serrations extending parallel to each other and to the side-faces of said blocks. Other forms of joints may also be provided. The blocks 12 21 form connecting members between said door-members, and are arranged'in pairs. In assembling the The metal of the door-members is door-members, they are so positioned that the blocks 12 and 21 of the respective pairs of said connecting members are out of radial line with each other, whereupon respective turning is caused between the door-menibers for bringing said blocks of said respective pairs of connecting members into coincident radial positions, and thereby causing relative sliding movement between the adjacent faces of said blocks.

34 are positioning blocks arranged to span the joints between the connecting members on the respective door-members for preventing relative turning of the door-members, the positioning-blocks being received in the recesses 15 22. The adjacent end-walls 35 3G of the connecting-blocks are preferably convergingly tapered, the ends 37 of the positioning blocks 34 being similarly tapered. Screws 38 are received in threaded apertures 39 in the connecting webs 13 and are arranged to draw the positioning blocks 34 between the converging adjacent end-faces of the connecting members for locking the inner and outer door-members securely in relative positions.

The door-opening comprises an outer tapered wall 40 and an inner tapered wall 41, separated by an annular shoulder 42. The outer door-member has a tapered periphery 43, whichA lits the outer tapered wall 40, while the inner peripheral edge 4.-'1- thereof is arranged to engage the shoulder 42 when the door is closed. The inner doormember has a tapered periphery 45 which is arranged to iit the inner tapered wall 41, and said inner door-member is arranged to enter said inner tapered wall so as to be spaced from said shoulder a distance corresponding to the distance between said inner and Outer door-members, whereby the result is obtained that even if said outer doormember should be blown off, the safe is still 'closed by the inner door-member.

There is a suitable combination lock 51 which is located in the space between the inner and outer door-members at one side thereof. The bolt 52 of said lock enters an aperture in the door-jamb in usual manner, and is used as a day-lock, and is operated by a knob 53 outside the outer door-member. A time-lock 54 is located centrally at the inside of the inner door-member, the bolts 55 whereof also enter suitable apertures in the door-jamb, in usual manner, there being however preferably no connection between the time-lock or its mechanism and the outside of the inner door-member, this inner door-member being preferably imperforate within the longitudinal projections of the inner walls of the connecting blocks between said door-members. The space between said door-members is increased by a recess 56 in the under face of said outer door-member for accommodating said lock 51.

The combination-lock 51 has an outer bar 63 comprising laterally extending wings 64 overlapping the adjacent ends of t-he connecting members adjacent thereto, screws 65 passing through said wings and into said connecting members, securing said lock 51 in place.

There is a central space (i9 between the connecting members which is in axial plane wit-h the time-lock 541-. A strip of the height of the space between the door-members is received about the inner end of the co1nbination-lock o1 and connects with the ends of the connecting members which are adjacent to said lock. The space between the door-members and within the connecting members and strip 70 may, if desired, be filled with a iilling 71, which is a nonconductor, or substantially so, of heat or electricity, for instance a hydraulic cement mixture. The filling 71 may be introduced into said space through an aperture 72 in the web 111 for filling the middle space 69.

The inner end of the inner door-member is provided with lugs 79 and the wall of the door-opening is provided with lugs 80. These lugs are relatively in different positions radially of the door when said door is ready for being opened or closed, but when the door is locked, the lugs respectively on the door and wall of the dooropening are brought into similar radial positions, the door being turned by suitable mechanism, not shown because well known, for bringing the lugs on the door behind the lugs in the wall of the door-opening, the lugs in the wall of the door-opening being received in an annular recess 81 in the peripheral face of the inner door-member.

Our improved construction permits the connection between the inner and outer doormembers to be made of such strength relatively to the door-members that the connection will give way prior to collapse of the inner door-member or its inner locking mechanism, while it permits this connection to be made of the desired strength for its purposes.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In combination, a round safe-door comprising inner and outer door-members, connecting-pieces secured to the opposing faces of said door-members spacing said doormembers apart and forming a central fillingspace therebetween, there being a fillingchannel between said central filling-space and the periphery of said door, a non-conducting filling of the character described in said central filling-space received through said filling-channel, the said inner doormember being imperforate within the longitudinal projection of said central fillingspace, and a time-lock secured to the inner end of said inner door-member and separated froin said filling-space by said imperforate portion of said inner door-member and from said outer' door-member by said non-conducting filling and imperforate portion of said inner door-member, the said non-conducting filling, imperforate portion of said inner door-member and time-lock being located in positions coincident with the rotary axis of said door, substantially as and for the purpose described.
